Estimates are an important part of mathematics. They help to give an approximate idea of a result without having to calculate an exact answer. In mathematics, an estimate is a rough calculation that is not completely accurate, but still provides a general idea of the size, amount, or degree of something. Estimates are very useful in everyday life, as they allow one to make a quick decision without having to go through the time consuming process of calculating an exact answer. Estimating also allows one to make quick predictions, forecast numbers, and plan for future events. Estimating can save time and money and is an essential skill for anyone studying math.
